m68k: coldfire: return success for clk_enable(NULL)

2021-09-15T08:00:51Z

[ Upstream commit f6a4f0b424df957d84fa7b9f2d02981234ff5828 ] The clk_enable is supposed work when CONFIG_HAVE_CLK is false, but it returns -EINVAL. That means some drivers fail during probe. [ 1.680000] flexcan: probe of flexcan.0 failed with error -22 Fixes: c1fb1bf64bb6 ("m68k: let clk_enable() return immediately if clk is NULL") Fixes: bea8bcb12da0 ("m68knommu: Add support for the Coldfire m5441x.")

m68k: let clk_enable() return immediately if clk is NULL

2021-02-07T22:15:17Z

Similar to commit<742859adc721>("m68k: let clk_disable() return immediately if clk is NULL"). there should be a check for clk to prevent NULL pointer dereference. Signed-off-by: Defang Bo Signed-off-by: Greg Ungerer

m68k: remove timer_interrupt() function

2020-10-30T20:57:06Z

This gets passed to a number of init functions, but is ignored everywhere, so remove the function and change the mach_sched_init callback to take no arguments.

m68k: coldfire: use legacy_timer_tick()

2020-10-30T20:57:05Z

Replace the indirect function calls in the timer code with direct calls to the newly added legacy_timer_tick() helper for those that have not yet been converted to generic clockevents. This makes the timer code a little more self-contained. Tested-by: Greg Ungerer Reviewed-by: Linus Walleij Signed-off-by: Arnd Bergmann

m68knommu: include SDHC support only when hardware has it

2020-10-05T11:51:31Z

The mere fact that the kernel has the MMC subsystem enabled (CONFIG_MMC enabled) does not mean that the underlying hardware platform has the SDHC hardware present. Within the ColdFire hardware defines that is signified by MCFSDHC_BASE being defined with an address. The platform data for the ColdFire parts is including the SDHC hardware if CONFIG_MMC is enabled, instead of MCFSDHC_BASE. This means that if you are compiling for a ColdFire target that does not support SDHC but enable CONFIG_MMC you will fail to compile with errors like this: arch/m68k/coldfire/device.c:565:12: error: ‘MCFSDHC_BASE’ undeclared here (not in a function) .start = MCFSDHC_BASE, ^ arch/m68k/coldfire/device.c:566:25: error: ‘MCFSDHC_SIZE’ undeclared here (not in a function) .end = MCFSDHC_BASE + MCFSDHC_SIZE - 1, ^ arch/m68k/coldfire/device.c:569:12: error: ‘MCF_IRQ_SDHC’ undeclared here (not in a function) .start = MCF_IRQ_SDHC, ^ Make the SDHC platform support depend on MCFSDHC_BASE, that is only include it if the specific ColdFire SoC has that hardware module.
